I am trying to set the 500 (Internal Server Error) custom error pages. When I do so, only 500;12 to 500-19 are changed, but 500 and 500;100 are left untouched. Why is this?
The admin will need to set these up under master properties, so that it is not a "default", but actually has a page allocated to it. Doing this will mean Helm can see it, and therefore update it.
